EILET M. TORKELSON AND BASIL MEIGS, OF WASHINGTON, DISTRICT OF COLUMBIA.

DISK WHEEL.

Application filed November 20, 1922. Serial No. 602,123.

To all whom it may concern:

Beit known that we, EILET M. TORKEL- SON and Basin MEIGS, citizens of the United States, residing at Washington, District of Columbia, have invented certain new and useful Improvements in Disk "Wheels, of which the following is a specification.

This invention relates to vehicle wheels, and more particularly to a novel improvement in disk wheels for automobiles.

A primary object of the invention is to provide a'simple and practical construction, wherein the hub and axle nut are concealed, thereby providin a full stream line effect to the wheel and materially enhancing its attractive and ornamental features without sacrificing any of its advantages as to strength, durability, and as a matter of fact also facilitating the tirechanging operation when necessary or desired.

Another object of the invention is to provide a noveldemountable rim construction which carries the cover disk that constitutes the outer face of the wheel and therebyconceals the hub and axle part of the vehicle.

A further object of the invention is to provide novel means for insuring the proper placing of-the valve stem in position when placing or removing the tire on the wheel.

- With the above and other objects in view i h ill more readily appear as the nature of 'the' invention is better understood, the same consists in the novel construction, combination and arrangement of parts, hereinafter more fully described, illustraton the line 5-6 of Figure 4.

Figure 6 is a detail sectional view taken on the line 6'6 of Figure 2.

Similar reference characters designate corresponding parts throughout the several figures of the drawings;

As previously indicated, one of the distinctive features of the invention is to make a disk wheel having a full stream line effeet, that is, a wheel in which the hub and axle-cap is entirely concealed so that the outer face of the disk presents a smooth uninterrupted and unbroken appearance, thereby contributing materially to the ornamental and attractive features of the wheel. It will of course be understood that the foregoing general object may be carried out in various ways, but the primary features involve the provision of a main disk A, a tire carryin rim B and an outer streamline cover That is to say, the invention has primarily in view a main disk A which assumes the greater part of the wheel load and also carries the hub of the wheel together with the outer cover disk 0 which is preferably made a gart of the wheel by attachment to the rim or its equivalent.

In the general organization shown in the accompanying drawing 1 designates a hub having a flange 2 adapted to carry therewith a main or primary load sustaining disk A the same being attached thereto by the bolts 3 or by any equivalent fastening means known and available in the art. This main disk A is preferably of dished or bowed formation at its central part and terminates in a felly flange 4: which is preferably slightly inclined as indicated at 5 to provide an inclined seat for the main section 6 of the rim unit B.

The said main rim section 6 is preferably provided at one edge with the integral flange 7 for engaging one of the tire beads and the opposite side thereof is constituted by the flange 8 of the removable tire looking ring 9 which is held to the main section 6 by suitable bolts 10 having the nuts 11 thereon for engaging with the inner face of the depending retaining flange portion 12 of the main section 6. As shown in Figure 2 the said depending retainin flange 12 is provided with a recessed shou A. Thus, the combined rim unit B and coverdisk C are securely locked to the main disk A by means of the fastening bolts 16 which are insertable through the clearance opening 17 provided in the locking'ring 9. The fastening bolts 16 therefore only serve to clamp the combined rim unit and cover to the main disk while the bolts 10 serve to hold and clamp the tire locking ring 9 to the main rim 6.

In connection with the retaining ring 12 of the main rim 6 it will be observed that this ring carries the cover disk 0 having the depressed flange portion 12 that provides a seat for the tire locking ring 9, and is also provided with an enlarged or bowed central portion- C which covers and overlies the hub 1 and axle part within the hub.

The provision of separate sets of bolts 10 and 17 for respectively holding the two sections of the rim B together and locking the entire rim to the main disk A has the advantage of permitting the rim B to be removed from and replaced on the main disk as a unit, without manipulatin the bolts 10 when a tire change is require In other words the combined rim and cover structure which carries the tire can be removed as a unit by simply manipulating the bolts 17 It will therefore be apparent that the primary features of the present invention heretofore outlined contemplate the main disk A having the felly flange 4 for receiving thereon the combined rim and cover structure B and C, the cover portion 0 being carried with the rim B, and the latter in turn consisting of separable sections 6 and 8 which permit of the placing and removal of a tire therefrom.

As further showing the range of modification of the invention reference may be had to Figs. 4 and 5 of the drawings wherein all of the essential features and characteristics of the invention are conserved but the means of locking the tire on the rim is different from that disclosed in Figs. 1 and 2.

Upon inspection of Fig. 4 it will be observed that the main disk A having the felly flange 4 is adapted to receive the combined rim and cover unit B'C in such a manner that the .rim B may be locked directly to the main disk A b a single series of bolts 18 which are adapte to engage with the lugs 19 carried by the felly-flange 4.

In the modified arrangement shown in Figs. 4 and 5 therefore it will be seen that the rim B consists of the main rim section 6* having theintegral flange 7 and a split locking ring 9" adapted to fit in a seat on the rim for the purpose of holding the tire in place. The depending retaining flange 12 of the said main rim section 6 carries the convexed cover disk C as indicated at 20, and, as previousl explained, the ring 12 is locked to the fe ly-flange by means of the bolts 18 and lugs 19. This arrangement eliminates the series of bolts corresponding to the bolts 10 in Fig. 1, but the essential feature of the combined rim and cover disk is conserved.

Another distinctive feature of the invention is shown in Figs. 2 and 6 of the draw ings wherein one of the sections of the rim B is provided with an openin 21 for the valve stem of the tire, the sai openin 21 communicating with a guide sleeve 23 w ich is preferably of elliptical cross-section as shown in Fig. G'and serves to guide the valve stem through the felly-flange 4 and into the valve access depression 24 in the load sustam ng disk A thereby to prevent any poss1b1l1t of the valve stem being caught by the e ges of the openings in the felly-flange or the 'wall 24 of the disk as the rim is placed on the wheel. By reason of the elliptical shape of the guide the insertion of the valve stem is facilitated since the valve stem is usually held at an angle to the plane of the rim opening when the tire is applied. It will also be observed that the disk at the mouth of the stem guide sleeve 23'is made flat as indicated at w to facilitatethe placing thereon of the usual clamping nut carried by the valve stem but also'having the effect of sealmg or closing the mouth of the sleeve to prevent the accumulation of dirt therein.

It will be observed from Figures 2 and'4 of the drawings that the inner disk member is preferably reversel periphery thereby pro ucing a spring effect for said inner disk member, while the outer disk member which is independent of the hub is connected with a part of the rim. This provides a construction which will yield to and absorb excessive shocks, thus avoiding fracture or breakage which would be likely to occur in a more rigid structure from such causes.

From the foregoing it is believed that the novel features and advantages of the invention will be readily apparent to thoseskilled in the art, andit Wlll of course be understood that changes in the form, proportion and minor details of construction may be resorted to without departing from the spirit of the invention or scope of the appended claims.
